Two Major Studies to Be Presented at ESMO 2016 Congress Presidential Symposium Demonstrate Potential of Merck’s KEYTRUDA® (pembrolizumab) for the First-Line Treatment of Metastatic Non-Small Cell Lung Cancer in a Broad Range of Patients

KENILWORTH, N.J.--(BUSINESS WIRE)--Merck (NYSE:MRK), known as MSD outside the United States and Canada,
today announced results from two major studies of KEYTRUDA®
(pembrolizumab), the company’s anti-PD-1 therapy, in the first-line
treatment of patients with metastatic non-small cell lung cancer (NSCLC)
at the ESMO 2016 Congress, the annual meeting of the European Society
for Medical Oncology:

In KEYNOTE-024, which evaluated squamous and non-squamous NSCLC
patients whose tumors expressed high levels of PD-L1 (tumor proportion
score, or TPS, of 50 percent or more), KEYTRUDA provided a 50 percent
reduction in the risk of disease progression or death and a 40 percent
reduction in the risk of death compared to platinum doublet, the
current standard of care. These data were also published today in The
New England Journal of Medicine. Based upon the results observed
from KEYNOTE-024, to date KEYTRUDA is the only anti-PD-1 to
demonstrate superior progression-free survival (PFS) and overall
survival (OS) compared to chemotherapy for the first-line treatment of
both squamous and non-squamous NSCLC in patients whose tumors express
high levels of PD-L1 and do not express EGFR or ALK genetic
aberrations.

In KEYNOTE-021, Cohort G, which included patients with metastatic
non-squamous NSCLC regardless of PD-L1 expression level, KEYTRUDA
(pembrolizumab) plus chemotherapy (carboplatin plus pemetrexed)
achieved a 55 percent objective response rate (ORR) compared to 29
percent for chemotherapy alone, the standard of care, and reduced the
risk of disease progression or death by 47 percent. To date, KEYTRUDA
is the only anti-PD-1 therapy to demonstrate superior efficacy in
combination with chemotherapy compared to chemotherapy alone in
patients receiving first-line treatment. These data were published
today in The Lancet Oncology.

“Chemotherapy has been the standard treatment for most patients with
advanced non-small cell lung cancer for decades, but survival rates
remain low,” said Dr. Roger M. Perlmutter, president, Merck Research
Laboratories. “Our new data suggest that KEYTRUDA treatment can offer
meaningful improvement over chemotherapy in a broad array of patients.
In this sense, these studies may represent a turning point in worldwide
efforts to control lung cancer. We sincerely thank the patients and the
clinical investigators for their participation in our studies. Together
we are working to improve the health of more and more patients with
cancer.”

Merck has submitted KEYNOTE-024 data to regulatory agencies in the
United States, Europe, and Japan. The U.S. Food and Drug Administration
has granted Breakthrough Therapy Designation and Priority Review, with a
PDUFA, or target action, date of Dec. 24, 2016.

Merck is currently advancing multiple registration-enabling studies in
NSCLC with KEYTRUDA as monotherapy and in combination, including the
combination of KEYTRUDA plus a platinum/pemetrexed-based chemotherapy
regimen in patients with previously untreated, non-squamous NSCLC in the
ongoing phase 3 KEYNOTE-189 trial. The KEYTRUDA clinical development
program includes more than 350 clinical trials across more than 30 tumor
types, including more than 100 trials that combine KEYTRUDA with other
cancer treatments.

KEYNOTE-024: Data Showed KEYTRUDA was Superior to Chemotherapy for
PFS and OS in First-Line Treatment of Metastatic NSCLC

KEYNOTE-024 included 305 patients who were previously untreated and
whose tumors expressed high levels of PD-L1 (TPS of 50 percent or more).
Patients were randomized to receive a 200 mg fixed dose of KEYTRUDA
every three weeks (n=154) or four to six cycles of investigator’s choice
of one of five platinum-based chemotherapy regimens (n=151): carboplatin
or cisplatin plus pemetrexed, carboplatin or cisplatin plus gemcitabine,
or carboplatin plus paclitaxel. Pemetrexed maintenance therapy was
permitted for patients with non-squamous histologies. Patients
randomized to the control arm had the option of crossing over to
KEYTRUDA (pembrolizumab) upon disease progression. The median follow-up
was 11.2 months (range, 6.3-19.7). The primary endpoint was PFS;
secondary endpoints were OS, ORR, and safety.

The findings published in The New England Journal of Medicine
demonstrated that KEYTRUDA reduced the risk of progression or death by
50 percent compared to chemotherapy (HR, 0.50 [95% CI, 0.37-0.68];
p<0.001). The median PFS for KEYTRUDA was 10.3 months (95% CI, 6.7-not
reached) compared to 6.0 months for chemotherapy (95% CI, 4.2-6.2). At
six months, 62.1 percent of patients treated with KEYTRUDA were alive
and had no disease progression (95% CI, 53.8-69.4) compared to 50.3
percent of those receiving chemotherapy (95% CI, 41.9-58.2). This
benefit was observed in all study subgroups.

Additionally, KEYTRUDA resulted in a 40 percent reduction in the risk of
death compared with chemotherapy (HR, 0.60 [95% CI, 0.41-0.89];
p=0.005); this finding includes the 66 patients (43.7%) on the
chemotherapy arm who crossed over in-study to receive KEYTRUDA once
their cancer had progressed; median OS was not reached in either group.
Further, ORR was 44.8 percent for patients receiving KEYTRUDA (95% CI,
36.8-53.0), including six complete responses, compared to 27.8 percent
with chemotherapy (95% CI, 20.8-35.7), including one complete response.

“These data from KEYNOTE-024 demonstrate the potential of KEYTRUDA to
change the way non-small cell lung cancer is currently treated,” said
Dr. Martin Reck, head of the thoracic oncology dept., LungenClinic
Grosshansdorf, Germany, and lead author of TheNew England
Journal of Medicine paper. “This provides additional evidence that
testing for PD-L1 levels should become standard in lung cancer at first
diagnosis to guide treatment decisions.”

Additional Findings and Safety Information from KEYNOTE-024

The safety of KEYTRUDA was consistent with what has been seen in
previous trials among patients with metastatic NSCLC. The most common
treatment-related adverse events for KEYTRUDA were diarrhea (n=22),
fatigue (n=16), and pyrexia (n=16). Grade 3-5 treatment-related adverse
events for KEYTRUDA included diarrhea (n=6) and pneumonitis (n=4). There
was one treatment-related death in a patient receiving KEYTRUDA (cause
unknown).

Additionally, based on an analysis of duration of response, a
pre-specified exploratory endpoint, the median duration of response was
not reached with KEYTRUDA (range, 1.9+ to 14.5+ months). The median
duration of response with the chemotherapy group was 6.3 months (range,
2.1+ to 12.6+). Median time to response was 2.2 months for both groups.

About KEYNOTE-024

KEYNOTE-024 is a randomized, phase 3 study (ClinicalTrials.gov,
NCT02142738) evaluating KEYTRUDA (pembrolizumab) as monotherapy compared
to standard of care platinum-based chemotherapy in the treatment of
patients with metastatic NSCLC. Patients enrolled were those who had
received no prior systemic chemotherapy treatment for their advanced
disease, whose tumors did not harbor an EGFR sensitizing mutation or ALK
translocation, and whose tumors expressed high levels of PD-L1 (TPS of
50 percent or more) as determined by a central laboratory using an FDA
approved companion diagnostic, the Dako PD-L1 IHC 22C3 PharmDx test,
from Agilent Technologies.

KEYNOTE-021, Cohort G, included 123 previously untreated patients with
metastatic non-squamous NSCLC regardless of PD-L1 expression and whose
tumors did not have EGFR mutations or ALK translocations. Patients were
randomized to receive KEYTRUDA plus platinum doublet chemotherapy with
pemetrexed and carboplatin (n=60) or platinum doublet chemotherapy alone
(n=63). Patients randomized to the chemotherapy-only arm had the option
of crossing over to KEYTRUDA monotherapy upon disease progression. The
median follow-up was 10.6 months (range, 0.8-19.3).

The findings published in The Lancet Oncology demonstrated that
ORR nearly doubled by adding KEYTRUDA to chemotherapy, with an ORR of 55
percent (n=33/60) compared to 29 percent (n=18/63) for chemotherapy
alone (treatment difference 26%, 95% CI, 9-42%, p=0.0016); all responses
were partial. Median duration of response was not reached in either
group (range, 1.4+-13.0+ for KEYTRUDA plus chemotherapy; 1.4+-15.2+ for
chemotherapy alone). Responses in both groups were durable, with 88
percent (n=29/33) of responders in the KEYTRUDA plus chemotherapy group
and 78 percent (n=14/18) of responders in the chemotherapy alone group
experiencing ongoing response at the time of data cut-off.

Additionally, the KEYTRUDA combination significantly reduced the risk of
disease progression or death compared to chemotherapy alone (hazard
ratio 0.53, 95% CI, 0.31-0.91, p=0.0102). Median PFS was 13.0 months
with KEYTRUDA plus chemotherapy compared to 8.9 months with chemotherapy
alone. OS was similar between the two arms, with 92 percent survival at
six months in both, and 75 percent and 72 percent survival at 12 months
in the KEYTRUDA combination and chemotherapy alone, respectively.

Of treated patients on the KEYTRUDA (pembrolizumab) plus chemotherapy
arm, 47 percent remained on treatment as of the cut-off date, compared
to 31 percent on chemotherapy alone. Of the treated patients who
discontinued treatment on the chemotherapy-only arm, 52 percent
(n=32/62) subsequently received anti-PD-L1 therapy, with 32 percent
crossing over to KEYTRUDA monotherapy as allowed by the study protocol
and 19 percent receiving it outside of study crossover.

“The results from KEYNOTE-021 show that pembrolizumab plus chemotherapy
nearly doubled the number of patients responding to treatment than
chemotherapy alone,” said Dr. Corey Langer, director of thoracic
oncology and professor of medicine at the Hospital of the University of
Pennsylvania and lead author of The Lancet Oncology paper. “We
are now gaining a better understanding that pembrolizumab combined with
chemotherapy may play an important role in the first-line treatment of
patients with non-small cell lung cancer.”

Additional Safety Information from KEYNOTE-021, Cohort G

The most common treatment-related adverse events (occurring in at least
15% of patients) for KEYTRUDA plus chemotherapy were fatigue, nausea,
anemia, rash, vomiting, diarrhea, increased AST, constipation, decreased
appetite, increased ALT, dysgeusia, and decreased neutrophils. Grade 3-4
treatment-related adverse events in this arm included fatigue, nausea,
anemia, rash, vomiting, increased AST, increased ALT, and decreased
neutrophils. The most common immune-mediated adverse events in patients
receiving KEYTRUDA plus chemotherapy were hypothyroidism and
hyperthyroidism. Additionally, pneumonitis, infusion reactions, and
severe skin toxicity were noted. These immune-mediated adverse events
occurred at similar rates to patients receiving KEYTRUDA as a single
agent. There was one treatment-related death from sepsis in a patient
receiving KEYTRUDA plus chemotherapy, and two (one from sepsis and one
from pancytopenia) in patients receiving chemotherapy alone.

About KEYNOTE-021, Cohort G

Cohort G of the multicenter, open-label, phase 1/2 multi-cohort
KEYNOTE-021 study evaluated the efficacy and safety of KEYTRUDA in
combination with pemetrexed and carboplatin compared with pemetrexed and
carboplatin in patients with metastatic, non-squamous, EGFR- and
ALK-negative NSCLC in the first-line treatment setting. Patients were
randomized 1:1 to four cycles of KEYTRUDA (200 mg plus carboplatin AUC 5
(5 mg/mL/min) plus pemetrexed 500 mg/m2 every three weeks),
or carboplatin plus pemetrexed alone, followed by maintenance pemetrexed
with or without KEYTRUDA. Randomization was stratified by PD-L1
expression (positive expression defined as TPS of one percent or more;
negative expression defined as TPS of less than one percent). Patients
randomized to the chemotherapy arm were allowed to cross over to
KEYTRUDA (pembrolizumab) monotherapy if they experienced disease
progression. Response was assessed by blinded, independent central
review using RECIST 1.1 every six weeks for the first 18 weeks, every
nine weeks through the first year, and every 12 weeks in the second
year. The primary endpoint was ORR; secondary endpoints included PFS,
duration of response, and OS.

About KEYTRUDA® (pembrolizumab)

KEYTRUDA is a humanized monoclonal antibody that works by increasing the
ability of the body’s immune system to help detect and fight tumor
cells. KEYTRUDA blocks the interaction between PD-1 and its ligands,
PD-L1 and PD-L2, thereby activating T lymphocytes which may affect both
tumor cells and healthy cells.

KEYTRUDA is administered as an intravenous infusion over 30 minutes
every three weeks for the approved indications. KEYTRUDA for injection
is supplied in a 100 mg single use vial.

KEYTRUDA Indications and Dosing

Melanoma

KEYTRUDA is indicated for the treatment of patients with unresectable or
metastatic melanoma at a dose of 2 mg/kg every three weeks.

Lung Cancer

KEYTRUDA is indicated for the treatment of patients with metastatic
non-small cell lung cancer (NSCLC) whose tumors express PD-L1 as
determined by an FDA-approved test with disease progression on or after
platinum-containing chemotherapy, at a dose of 2 mg/kg every three
weeks. Patients with EGFR or ALK genomic tumor aberrations should have
disease progression on FDA-approved therapy for these aberrations prior
to receiving KEYTRUDA. This indication is approved under accelerated
approval based on tumor response rate and durability of response. An
improvement in survival or disease-related symptoms has not yet been
established. Continued approval for this indication may be contingent
upon verification and description of clinical benefit in the
confirmatory trials.

Head and Neck Cancer

KEYTRUDA is indicated for the treatment of patients with recurrent or
metastatic head and neck squamous cell carcinoma (HNSCC) with disease
progression on or after platinum-containing chemotherapy at a fixed dose
of 200 mg every three weeks. This indication is approved under
accelerated approval based on tumor response rate and durability of
response. Continued approval for this indication may be contingent upon
verification and description of clinical benefit in the confirmatory
trials.

Hypophysitis occurred in 1 (0.2%) of 550 patients, which was Grade 3 in
severity. Monitor patients for signs and symptoms of hypophysitis
(including hypopituitarism and adrenal insufficiency). Administer
corticosteroids and hormone replacement as clinically indicated.
Withhold KEYTRUDA for Grade 2; withhold or discontinue for Grade 3 or 4
hypophysitis.

Hyperthyroidism occurred in 10 (1.8%) of 550 patients, including Grade 2
(0.7%) or 3 (0.3%) hyperthyroidism. Hypothyroidism occurred in 38 (6.9%)
of 550 patients, including Grade 2 (5.5%) or 3 (0.2%) hypothyroidism.
Thyroid disorders can occur at any time during treatment. Monitor
patients for changes in thyroid function (at the start of treatment,
periodically during treatment, and as indicated based on clinical
evaluation) and for clinical signs and symptoms of thyroid disorders.
Administer replacement hormones for hypothyroidism and manage
hyperthyroidism with thionamides and beta-blockers as appropriate.
Withhold or discontinue KEYTRUDA for Grade 3 or 4 hyperthyroidism.

Type 1 diabetes mellitus, including diabetic ketoacidosis, occurred in 3
(0.1%) of 2117 patients. Monitor patients for hyperglycemia or other
signs and symptoms of diabetes. Administer insulin for type 1 diabetes,
and withhold KEYTRUDA and administer anti-hyperglycemics in patients
with severe hyperglycemia.

Other clinically important immune-mediated adverse reactions can occur.
For suspected immune-mediated adverse reactions, ensure adequate
evaluation to confirm etiology or exclude other causes. Based on the
severity of the adverse reaction, withhold KEYTRUDA and administer
corticosteroids. Upon improvement to Grade 1 or less, initiate
corticosteroid taper and continue to taper over at least 1 month. Based
on limited data from clinical studies in patients whose immune-related
adverse reactions could not be controlled with corticosteroid use,
administration of other systemic immunosuppressants can be considered.
Resume KEYTRUDA when the adverse reaction remains at Grade 1 or less
following corticosteroid taper. Permanently discontinue KEYTRUDA for any
Grade 3 immune-mediated adverse reaction that recurs and for any
life-threatening immune-mediated adverse reaction.

Based on its mechanism of action, KEYTRUDA can cause fetal harm when
administered to a pregnant woman. If used during pregnancy, or if the
patient becomes pregnant during treatment, apprise the patient of the
potential hazard to a fetus. Advise females of reproductive potential to
use highly effective contraception during treatment and for 4 months
after the last dose of KEYTRUDA.

KEYTRUDA was discontinued due to adverse reactions in 14% of 550
patients. Serious adverse reactions occurred in 38% of patients. The
most frequent serious adverse reactions reported in at least 2% of
patients were pleural effusion, pneumonia, dyspnea, pulmonary embolism,
and pneumonitis. The most common adverse reactions (reported in at least
20% of patients) were fatigue (44%), cough (29%), decreased appetite
(25%), and dyspnea (23%).

It is not known whether KEYTRUDA is excreted in human milk. Because many
drugs are excreted in human milk, instruct women to discontinue nursing
during treatment with KEYTRUDA and for 4 months after the final dose.

Safety and effectiveness of KEYTRUDA have not been established in
pediatric patients.
